I'm getting an error when trying to add administrator accounts through ZCC based on user(s) in a user source.
Error states: A few administrator(s) might not have been created. For more details, see zcc.log

From the ZCC Log, it states:
[DEBUG] [03/22/2017 11:40:55.540] [1648] [ZENServer] [325] [__z_1_92__] [ZCC] [] [Unable to create the administrator Firstname Lastname. For details, see the zcc log.] [] [] [] [ZENServer]

Any ideas on what could be going on here?
